Application filed April 28, 1914. $0118.11). 834,949.

To all whom may concern:

. changing of straps of different material and colors is readily and quickly accomplished.

The main object of this invention is to provide a simple, economical, durable and eiiicient device for securely and safely fastening the ends of a strap of any suitable material or desirable color to a watch or other article, and at the same time allow the straps to be renewed or interchanged with great facility, at thewill of the wearer or user.

Another object of the-invention is to provide an improved detachable strap ternnnal provided with a hook, and means connected therewith adapted to carry the strap end in such proximity to the hook as topractically lock the hook to the article to which it is attached, thereby preventing the accidental detachment of the said hook.

A further object of the invention'is to furnish a detachable strap terminal device of metal for removably securing straps to a bracelet watch, said device comprising means for safely securing the strap to the watch, and means whereby the straps may be quickly renewed or interchanged, the said device beingof such style and shape as to .be in keeping with the shape of the watch.

The foregoing and such other objects as may occur from the ensuing descri tion are attained by the constructlon, com ination, arrangement and location of the parts hereinafter more fully described, illustrated in the accompanying drawings forming a part of this specification, and particularly pointed out in the claim appended hereto.

With reference to the drawings:-

Figure 1, is a plan view of a strap watch bracelet embodying my invention, showing straps broken away.

F1g. 2, is an inverted plan view of the construction shown in Fig. 1.

Fi' 3, is an enlarged longitudinal sec- #10113? view of my improved detachable strap terminal and safety hook showing in cross section the end of a strap secured thereto.

Fig. 4, 1s a transverse section of the device shown .in Fig. 3, showing it hooked to oneside of a portion of a watch case.

Fig. 5, is an enlarged perspective view of Y the detachable strap terminal and safety hook. Fig. 6, is an enlarged plan view of a sllghtly modified form. of detachable strap termmal and safety hock.

Fig. 7, 1s a transverse sectionof the device shown in Fig. 6, and

Fig. 8, is an enlarged plan view of the strap bracelet buckle'showing the buckle removed from the strap.

Similar characters of reference are employed to designate like or the same parts throughout the several views of the drawm s.

y reference to Figs. 1 and 2 of the drawmgs it will be seen that there is illustrated a top plan view and a reverse plan, respectively, of a strap watch bracelet, showing the watch A removably secured to theadjacent ends of the straps a, a,'by my'improved detachable strap terminal and safety hook devices B and'C, the device B being the preferred form, and C constituting aslightly modified form hereinafter more fully described. The strap a is provided at its outer end with a buckle D, the outer end of the strap a having a series of perforations therethrough thus furnishing means whereby it will be understood the bracelet may readily be secured to the wrist of the" wearer.

The detachable strap terminal and safetyv hook device B consists of a transverse bar 6 provided at its central portion with an integral depending hook member 0, and terminatlng n integral depending portions 03 and d, the lower end of the portion at having I by the 1 member the outer end of the meimberg is) air; outware'g integral rojection i a a te engag nger for manipulating. the said assume the unlocked and locked position.

As shown in Fig. 8} of the drawings the hollow member e carries a coiled spring withimwhich is adapted to rest against the inner end of the sl1dable member 7, and

es to force the latter outward and retain it in locked" position. The looped end of the strap a. surrounds the hinged member e. and the strap may be cutout at the rear central portion of the loop to allow the end of the hook to substantially close up the space between the hinged member 6 and the hook c, as clearly shown in Fig. 4 of the drawings, thereby preventing the accidental nnhookmg of the detachable strap terminal device from the watch when the hinged j member is in its locked position.

When it is desired to renew or replace the old strap with a new one of a different color or material, it is simply necessary to engage the projection '75 with the fin er and force the slidable member f inward y thereby -un-- locking the hinged member 6 from the bar 6 and then swing it outward to the'position shown in Fig. 4:, when the strap may be slipped oil and readily removed, and a new strap adjusted thereon, after which the hinged member may be swung back into the locked position shown in Fig. 3.

The modified form of my improved detachable strap terminal and safety hookdevice shown in Figs. 6 and 7, shows a transverse ba-r G having at its central portion an integral depending hook member 0. and terminal integral projecting portions m, m,

on a plane with said bar, the portion at hav-' ing a member n hinged thereto, said member 1!. being locked to the'end m of the bar G by'the slidable membero, engaging with an opening in' the outer end of the projecting portion m, as clearly shown in Fig. 6, the terminal of the hook member a resting in such close proximity to the hinged member as to prevent the. accidental unhooking of the bar C from the watch or other article to which itpmay be attached.

Fig. 80f the drawings shows an enlarged and causing the hinged-member to.

areas view of the buckle D attached to the outer end of strap a, said buckle having a member:

l hinged to its inner end portion at r, and carrying a slidable member 8 adapted to lock and unlock the hinged member in order that the strap may readily be renewed or exchan It ll be understood that my detachable strap terminal and safety hook may be attached to various articles, such as neck ribbons connect% with. lockets, for iobs where the silk becomes soiled and has to be. renewed, for garters and numerous other. articles where ribbons, elasticand other similar materials are used for wear and it is desirable to renew or exchange the material employed.

Slight changes may be resorted to in the precise details of theconstruction herein described without departing from the spirit of my invention.

Having thus described my invention what I claim and desire to secure by Letters Patent is i A detachable strap terminal and safety hook for strap watch bracelets comprising, a metal bar having at each end thereof an integral right an le extension and an integral projecting hoo member at its central portion, one of said extensions having an opening therethrough, and the other extension carrying a hinged hollow member at its outer end, said hollow member being provided with a solid slida-ble' member adapted CHARLES L.
